Enumerations of the 4 Maha-yana dars`ana-s and of the 4 Vajra-yana Tantra-s are to be found in the Inner Kalacakra Tantra (by Vesna Wallace).

Idenfication as A-jivika of the Kala-cakra Tantra is based on that text's description (in the Outer Kalacakratantra PhD diss.) of the catapult, the catapult's use in combat to identify Skanda; the partitioned personification of the Guhya-samaja Tantra as Guhyaka-s to identify (as their leader) Kuvera in Ud-tara-Kuru; etc.
